ATTACHMENT FOR Janene MACHINES.

'Application filed January 27, 1926. Serial No. 84,230.

This invention relates to improvements in attachments for paper making machines and the objects of the invention are to provide a simply constructed and economical attachment for paper making machines where by the rope carriers on the rolls are more securely retained in position.

Further objects are to provide a simply constructed attachment whereby the ropes or cords for taking the paper over thedryer will be effectively maintained from slipping over the end of the roll or dryer and breaking the ropes or cords.

I'Vith the foregoing and other objects in view the invention consists essentially of a substantially semicircular plat-e adaptedto be rigidly attached to the frame of a paper making machine in that portion thereof where are provided the bearings for the paper carrying rolls. This plate is formed with a substantially horse-shoe sleeve on the inside designed to register with the outer periphery of the end of the dryer rolls sothat when the retaining cords or canvas 1s r inclined to slip over the ends down 1nto the journal and on to the bearings they will be prevented from so doing by the sleeve of the attachment plate. In other words our improved attachment rigidly secured to the frame automatically closes the gap between the end of-the dryer rolls and frame of the machine toact as a safety guide .for' the rope carriers.

Referring now to the drawings in which like characters of reference indicate corresponding parts in each Figure,

Figure 1 is a perspective view of a paper carrying roll with my improved attachment,

Figure 2 is a frontview, partly in section showing the attachment secured to the frame and extending outwardly to cover the gap between the bearing carrying frame and the end of the paper carrying roll journalled in the bearing,

Figure 3 is a perspective detail of the attachment plate, Y

Figure is an end view of rollers with ropes mounted thereon.

Referring now more particularly to the,

drawings in which a'preferred example of our mvention 1s illustratedlO deslgnates a paper carrying roll of an ordinary paper tering with. the end of the roller is our improved attachment rigidly mounted on the frame by bolts or the like l t and comprising,

as illustrated in Figure 3, a semi-circular plate 15, with suitable openings 16 therein toreceive the securing member, a partially open sleeve or collar 17, the length and circumference of which may be varied in any suitable manner according to existing con ditions.

In using our attachment the base or plate roll and the frame and so. preventing the ropes, cords or the like, used for holding the paper-carrier on the roll to slip off over the end and on to the bearings to get entangled with the spindle 11 and thus plug the machine causing considerable damage and often considerable expense.

As many changes could be made in the above construction and many apparently widely different embodiments of our invention, within the scope of the claims, con- 'structed without departing from the spirit or scope thereof. it is intended that all matter contained in the present specification and accompanying drawingsshall he interpreted in an illustrative and not in a limiting sense. I

'W hat we claim as our invention is:

1. In a paper making machinethe combination with a, frame having suitable bearings therein and aroll having a spindle journalled therein designed to be supported in said bearings, of a plate rigidly mounted on the frame and formed with an extension conforming to the contour of the roll and designed tobridge the space between the end of the roll and the frame.

2. In a devlceof the character described a plate or base of substantially semi-circular form and a collar formed on said plate ofsimilar formation but of greater circum ference than the plate.

In witness whereof we have hereunto our hands.
